MANUEL M. OARMONA Y VALLE, OF MEXICO, MEXICO.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 401,005, dated April 9,1889.

Application filed December 1, 1888.

To all whom, it may concern.-

Be it known that I, MANUEL M. OARMONA Y VALLE, of the city of Mexico,Mexico, have invented a new and Improved Double Automatic Car-Con pler,of which the following is a full, clear, and exact description.

The object of this invention is to provide an automatic car-coupler bymeans of which cars may be doubly coupled, and which may be applied toany of the known forms of coupler, and that, too,without interferingwith the action of the original couplers; and to the ends named theinvention consists, essentially, of a coupling-link and a couplinghookof novel construction, which link and hook are combined with adraw-frame when the coupler is applied to draw-heads not specially madeto coact therewith, all as will be hereinafter more fully described, andspeci fically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the' views.

Figure 1 is a plan view of my improved automatic coupler, the partsbeing represented as they appear when in the coupled position. Fig. 2 isa perspective View of my improved coupler. Fig. 3 is a perspective view,upon a smaller scale, of my coupler as it appears when removed from itsdraw-head. Fig. at is a perspective view of a saddle at times employedin connection with my coupler, the views above referred to illustratinga construction employed in connection with freight-cars.

Fig. 5 is a plan view of my improved automatic double couplerconstructed for use in connection with a passenger-car and arranged tocoact with a draw-head of ordinary form. Fig. 6 is a perspective view ofthe construction shown in Fig. 1, and Fig. 7 is a perspective view ofthe coupling attachment, representing it as it appears when removed fromthe draw-head.

Referring now to the construction shown in Figs. 1, 2, and 3, 10represents a draw-head and 11 a draw-bar of the form which I prefer touse in connection with my coupler, the draw-bar spring being shown at13, the follower-plates at 14, and the draw-bar cage at Serial No.292,581. (No model.)

15, keys 16 being arranged in the ordinary manner. Through the draw-head10 I form a bore or slot that is adapted to receive a coupling-pin, l7,normally held in the position shown in Fig. 1 by a spring, 18, saidspring abutting against a fixed stop that is carried by the car-body.

To the free end of the pin 17 I rigidly connect an inwardly andforwardly extending arm, 3, and upon the other end of the pin I mount alever, 19, at the forward end of which lever there is formed acoupling-link, 20. The rear end of the lever 19 is forked, as shown at21, to embrace a rod, 22, that is arranged for connection with thecar-body, or I could connect a spring, 23, (see Fig. 6,) to the rear endof the lever 19, said spring being connected to the car-body, and thetension of the spring being adjusted so that the link 20 would benormally held in about the position in which it is shown in thedrawings.

As two cars provided with my improved coupler approach to couple, theforward lengths of the coupling-links 20 will bear against the inclinedarms 3 of the couplingpins 17, and the pins will be moved against thetension of their springs 18 in the direction of the arrows shown in Fig.1, until the extending end a of each of the pins 17 clears the forwardlink length, after which the springs 18 will act to throw the pins 17 tothe position shown in the drawings. To unoouple, the pins are drawn inthe direction of the arrows by means of chains or rods 24:, that areconnected to the pins and extend outward through the springs, as shown.

In case it should be desired to couple cars in which the difference inheight is greater than half the height of the link 20, the spring 23(shown in Fig. 6) is employed instead of the rod 22, the links in thiscase being moved upward or downward by means of a lever that is placedagainst the drawhead as afulcrum and brought to bear again st thelink-lever 19.

In Figs. 5, 6, and 7 I illustrate a construction by means of which mycoupler may be applied to any of the well-known types of couplerswithout interfering with their action.

To this end I provide a saddle, 26, which is passed over the draw-headand formed with eyes 4, through which the coupling-pin 17 is passed,said pin extending beneath the drawhead. To the eyes 4 I connectrearwardlyextending auxiliary draw-bars 30, which pass through aperturesformed in the rear drawbar plate. The saddle 26 might be arranged belowthe draw-head and the pin 17 above without departing from the spirit ofmy invention.

Having thus described my invention,l claim as new and desire to secureby Letters Patent-- 1. The combination, with a draw-head,of acoupling-pin, a springarranged in connection with the pin, and acoupling-link pivot-ally connected to the pin, substantially asdescribed.

2. The combination, with a draw-head, of a coupling-pin formed with aforwardly-extending and inwardlydnclined arm, a spring arranged inconnection with the pin, and a coupling-link pivotally connected to thepin, substantially as described.

The combination, with a draw-head, of a coupling-pin provided with aforwardly-extending arm, auxiliary draw-bars through which the pinpasses, a saddle by which the draw-bars are connected, a lever pivotallymounted upon the coupling-pin, a link carried by the lever, and springsarranged in connection with the lever and coupling-pin, substantially asdescribed.

at. The combination, with a coupling-pin, of a link pivotally connectedthereto, auxiliary draw-bars through which the pin passes, and afollower-plate through which the draw-bars pass, substantially asdescribed.
